Filter

Filters themselves:
 * Gas Filter
 * Liquid Filter
 * Solid Filter
 * Loop filter – a modular automation design that outperforms filter buildings at the cost of space.
 * Mechanical filter – the other ways of filtering.
 * FILTER Gate – a timed delay automation module, not related to filtering directly.

Buildings, that process materials by filtering:
 * Carbon Skimmer – filters Carbon Dioxide with water.
 * Deodorizer – purifies Polluted Oxygen with Filtration Medium.
 * Desalinator – removes salt from Salt Water and Brine.
 * Water Sieve – purifies Polluted Water with Filtration Medium.
